Interictal epileptiform discharges (spikes) represent electrographic marker of epileptogenic brain tissue. In this work we developed a reliable automatic algorithm to detect high and low amplitude interictal epileptiform discharges in intracranial EEG recordings and designed a clustering method to extract spatial patterns of their propagation. Result show that this unsupervised approach is able to identify distinct sources of interictal epileptiform discharges and has the potential to increase the yield of presurgical examination by improved delineation of the irritative zone
